You make some assumptions about what I believe. What I see from the flat-earthers is a lack of trust in authorities, but they have to assume that millions of people who are doing science are lying whilst keeping the conspiracy silent. That's a big ask. Apparently some distrust NASA, but the science of astronomy goes back a long way and covers many cultures.

I did a certain level of science at school, so I know some principles even if I may not follow advanced topics. I do know that shining a laser at the Sun is pretty pointless as you would not be able to make it out against all the radiation pouring out. People were able to make accurate measurements long before lasers came along, but these may not be easy for an amateur to replicate. I also cannot look at some subatomic particles, but I did some observations of interactions at school such as Brownian motion and some types of radiation.

I'm not into religion or other supernatural things as those lack scientific validity. People can believe what they want as long as they do not force it on others.

If you don't trust people you never met then that limits what you can trust. Will you fly in a plane or accept medical treatment? Trust is vital for a working society, but has to be earned. Without science we would not be communicating now.

On balance I trust science more than random people on the internet. It has a better record of being right.
